Roger Toussaint’s getting-put-away party Friday night was not paid for by the cash- strapped union boss, but in stead with a little help from his friends, sources said yes terday.

Dennis Rivera, president of Local 1199, not only offered up the penthouse floor of his Midtown union digs for the booze-soaked bash, he agreed to cover much of the tab, a source close to the union told The Post.

A DJ spun Caribbean music as the TWU faithful dined on a catered Spanish and Italian meal.

Despite being told by 1199’s management not to bring alcohol to the festivities, TWU revelers said they tanked up in an act of “civil” disobedience. Some of Toussaint’s opponents had accused the TWU president of spending what little was left of the embattled union’s finances only days after a judge slapped the union with a $2.5 million fine and ordered the suspension of automatic dues collection.
